Abstract: 1,228,677. Laminates; seaming non-metallic sheet material. GRIESSER. 19 Aug., 1969 [22 Aug., 1968], No. 41269/69. Headings B5K and B5N. A composite web comprising a pair of superposed sheets joined at spaced intervals by parallel flexible strips welded by their edges to the superposed sheets is produced by causing the sheets to travel through a field of action of a heat-welding set interposing the joining strips between the sheets, causing the welding set to weld one edge of each strip to one sheet and the other edge of each strip to the other sheet and using a sheet of heat insulating material, e.g. asbestos or glass fibre material, to separate each edge, when being welded from the sheet to which it is not being welded. A trailing edge welding of a strip previously welded along its leading edge may be effected simultaneously with the leading edge welding of the next strip, the insulating material being interposed between the trailing edge of the previously welded strip and the leading edge of the next strip. In the drawing upper sheet 1 and lower sheet 2 travel between the upper jaw 3 supporting heating and pressure plate or blade 5 and lower jaw 4 supporting heating and pressure plate or blade 6. Leading edge 8 of strip 7 has already been welded to the lower face of sheet 1 and its trailing edge 9 is to be welded to the upper face of sheet 2. Leading edge 11 of strip 10 is to be welded to the lower face of sheet 1. When the jaws 3 and 4 of the welding set are brought together heated plate 5 welds edge 11 to sheet 1 and plate 6 welds edge 9 to sheet 2, the sheet of insulating material 12 preventing welding of the edges together. After the jaws are moved away insulating material 12 recedes so that the trailing edge 13 of strip 10 engages sheet 2 and the procedure is repeated. Roller binds permitting the passage of a variable quantity of light according to the relative position of the sheets may be produced using sheets of translucent of apertured material joined by less translucent or opaque strips. The superposed sheets and joining strips may comprise heatweldable plastic material at least for a portion thereof although if other materials are used or if the quantity of heat weldable material is not sufficient to effect heat welding further thermoplastic material may be applied.

Abstract: 1,230,520. Fuel elements. LE CARBONE LORRAINE. 8 Dec., 1969 [6 Dec., 1968], No. 59870/69. Heading G6C. A high-temperature nuclear reactor fuel element has the fuel present as a lining on the interior of a hollow graphite sphere with the remaining space within the sphere at least partially filled by expanded graphite. Such a fuel element is made by introducing a gum adhesive through a filling aperture 13 in a hollow graphite sphere 1 to coat the wall of the cavity 12, fuel particles 14 with a pyrocarbon covering then being introduced through the aperture and distributed uniformly over the adhesive-coated wall, followed by drying of the sphere 1 in an oven at a temperature of between 70 and 80 C. A lamellar complex of graphite 15 is then introduced into the sphere 1 and the aperture closed with a perforated cap 16. The cap 16 allows the evacuation of gases on the application of heat, but keeps the exfoliated graphite within the cavity 12. In one embodiment, the sphere 1 is heated to 1000 C. in a resistance furnace and a lamellar complex formed by the acid sulphate of graphite on flakes of graphite is introduced into the sphere. In Fig. 5 is shown the graphite 15 after expansion, filling the cavity 12. In an alternative embodiment (Fig. 7), expanded graphite 15 is introduced into the graphite sphere 1 coated internally with fuel 14, then through the aperture 13 a rigid tube is introduced, open at both ends, containing an elastic bladder 8. The bladder 8 is inflated and the expanded graphite 15 compressed against the cavity wall. This operation is repeated several times and the central space 27 is then filled by adding powdered expanded graphite and applying unidirectional compression, or by expansion of a lamellar complex.

Abstract: 1,266,186. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 1 July, 1970 [2 July, 1969; 8 Aug., 1969], Nos. 33362/69 and 39847/69. Heading H2K. A protective arrangement for a transformer system includes a detector which inhibits tripping when a transformer inrush current appears, the detector squaring the waveform of a "monitored" current quantity at a predetermined level and inhibiting tripping when the resulting rectangular pulses are not sufficiently close together. As shown the arrangement may comprise an auxiliary current transformer 12 and a circuit 13 providing a full-wave rectified signal representative of the difference between two phases of a transmission line having a substantial transformer loading. The rectified signal is applied to a high-set overcurrent detector 17 which squares the signal at a high level to effect the immediate operation of an output circuit 16 to cause the opening of circuit-breakers without any delay. The rectified signal is also applied to a low-set overcurrent detector 14 which squares the signal at a lower level, the resulting square pulses being fed to an integrator and level detector 15 to charge a capacitor, the detector 15 providing an output to the circuit 16 when the capacitor voltage exceeds a predetermined level. The detector 14 also supplies square pulses to a gap detector 18 in which a second capacitor charges in each interval between pulses. Should an interval be sufficiently long for the voltage of the second capacitor to reach a critical value, the detector 18 becomes effective to inhibit operation of the detector 15 by causing the discharge of its capacitor. In a further arrangement for the protection of a single transformer, Fig. 4, (not shown) having current transformers associated with the primary and secondary windings of the protected transformer and a comparator to provide an output to an integrator and level detector when a signal representing the difference current exceeds one representing the sum current, the gap detector is responsive to the difference signal to inhibit tripping. The high set detector also responds to the difference signal.  Both arrangements use transistor circuits, Figs. 2, 5 (not shown) and the principles underlying the invention are described with the aid of graphs, Figs. 3, 6 (not shown).

The rack comprises members 40, 42 together reciprocated laterally of the support by a motor 64. The member 42 has receptacles 74, 76, 78, 80 for the lower ends of rods, a rod end in a receptacle projecting a plunger 92 from the member 42 and keys 82 in the receptacles preventing rod rotation. A pin 102 is fixed to the member 42 in line with the plungers, and an adjustable stop 110 and a hook 116 are slidable together along the member 42. A stop 126 fixed to the support and a pin 132 extendable from the support co-operate with the stop 110. When the rack is not reciprocating to supply or remove rod from the drill string it is moved to the right of the support for storage until a part 118 of the hook engages the stop 126. To supply rod to the drill string the pin 132 is retracted. The rack is moved to the left its motion being limited by stop 110 engaging stop 126 and the hook engaging the plunger 92 associated with the receptacle nearest the drill string housing a rod end so that this receptacle is aligned with the drill string. The shank 18 of the motor 16 is screwed into the rod supported by the receptacle, the motor is raised to align the rod neck 70 with a slot 68 in the member 40 so that the rack may be moved to the right for storage. When all the receptacles are empty and rod is to be removed from the string, the pin 132 is projected and on movement of the rack to the left is engaged by the stop 110 so that on further movement the hook engages pin 102 and receptacle 80 is aligned with the string to receive rod. The rack is moved to storage and back towards the string so that the hook engages the plunger associated with the receptacle 80 to bring the receptacle 78 into line with the string. The reciprocating of the rack is repeated until it is full. The rack is reciprocated by a reversible hydraulic motor supplied with fluid from a pump the supply circuit incorporating pressure relief valves.
